I Leners Patent No. 109,496, amd November 22,v V1st-o.

IMPRovEMEN-r IN wine-MILLS.

The Schedule referred to in these Lettera Patent and making part of the same.

The nature of my invention consists in the construction and arrangement of a device for changing the position of the fans in a wind-mill automatically, according to the force of the wind, making them selt`- regulating, so as to run the machinery at all times with the same speed.

In order to enable others skilled iu the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring vto Ithe annexedl drawing, in whichf- Figure l is a side elevation, and

Figure 2, a vertical section through line a b, tig. l, of my machine.

A represents the circular hase, which is to revolve upon the stand B.

On the circular base A are standards C C, forming bearings for the crank-shaft D, upon the outer end of which is secured the wheel E,

This wheel is provided with arms G G, upon which the fans H H are hinged or otherwise pivoted.

rlhe fans are not hung upon the arms GG in their centers, but they are wider on one side' of the arms than on the other side, and at their inner ends on the wider sides they are connected by rods a a with a wheel,- I, which is placed upon the shaft D, revolving with it, but capable of being moved out or in on the same.

In the stand B is plvoted a lever, J, the inner end of which is shaped as a ring, b, and the outer cud provided with au adjustable weight, K.

A hook, rl, upon the lower end of a vertical rod, L, embraces the ring b of the lever J, said rod passing upward through a guide, c, attached to the circular base A, and its upper end is attached to a lever, M, which is forked, and the two arms pivoted on the upper side of the hase A, their ends passing into a groove on the hub of the wheel I.

The fans being wider on one side of the arms than on the other, causes the greater force of the wind to be upon the wider side of the fans, which has a tendency to turn them inwardly.

fly their tendency to turn inwardly, they crowd against the wheel I, through the connecting -rods a, a.

This causes the wheel I to slide upon the shaft D, and' react against the pronged or forked lever M. This lever reacts through the perpendicular rod L, and down upon the ring'b ofthe horizontal lever J, depressing or lowering the ring and elevating the outer end, with the weight K upon it.

By means of this weight the fans can be set with any desired force against the wind according to the power wanted, and when the wind exceeds the force of the fans or the power' of the weight below, the weight will be overcome, and will rise and let the fans turn inwardly, and the wind escape without iucreasing the velocity of the machinery.

When the wind hills the weight will fall, turning the fans outwardly, presenting more .surface to the windLand-keep up the velocity, and thus it becomes a self-regulator, adapting itself to Vevery variation of the wind.

Ihe machine is stopped by lifting up upon' the weighted lever, which-slides the vwheel I back upon t-heshaft and turns the fans edgewise to the wind.

The weighted levermust be fastened in position when the machine is at rest or disconnected from the `perpendicular rod L.

1t is, of course, understood that the machine is calculated to turn upon thestand withevery change ot wind.

The Aconnecting-rod or pitman, that is to work upon the crank of the shaft D, must extend down through and have its lower connection below the ring I) of the horizontal lever J, for, as4 the perthat connects with said ring, isv

pendicnlar rod L, hung on one side of the center at thel'top, it will describeA a circle as the machine turns upon the stand, and as the pitman on the crank is 'in the center, its position will be in the center of motion all the time, while the rod at'its side will describe a circle around it.

The ring -b, with which said perpendicular rod connects, gives a chance to make the connection any where on the circle as the wind changes.

The weighted lever' J must have a perfect bearing or fulcrum, so as to sustain a sidewise force when the -connection is at one side.

The weight K must be moved upon the lever to correspond with the place of connection upon the ring.

In a large machine-the connection with thevring is by means of two friction-rollers, which enables the perpendicular rod to change position easily upon the ring as the wind changes. v

vHaving thus fully described myinvention,

That I claim as new, and desire to seeure'by Let- '1n testimony -that I claim the foregoing I. have ters Entent, ishereunto set my hand this 26th day of April, 1870, 'lhe fans H H, placed upon the arms G Gr, as i JOHN R CLEMENT.
